III IIII'II UII-IIIII" WITNESS:

ATTCRNEY UNITED, STATES- PAT Em m c ISAAC 3; nvms, or AVA, mrssotm 1mm"! BARIL.

To all whom it coacemi Be it known that I, ISAAC H. EVANS, a

citizen of the United, States, residing at Ava, in the county of Douglas and State bf Missouri, have invented new and useful Improvements in Dairy Barns, of which the following is' a specification.

This invention relates to improvements in dairy barns, thegeneral object of the invention ,being to provide means for cleaning I the gutters by-the movement of the cows in reaching 'for their feed.

This object is obtained by hi'nging each stanchion at one end and movably supporting 'its other end so' that the stanchion will be rocked by the cow reaching for its feed with means for transmitting the movement of the stanchion to a conveyor placed in the gutter.

Another object of the invention is to provide novel means for hingedly connecting one part of each stanchion to its other part with means for regulating the movement of said movable part.

This invention also consists in certain other features of construction and in thecombination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1 is a diagrammatic plan view of a part of the barn supplied with my invention.

Figure 2is a section on line 22 of .Figure 1.

Figure 3 is asection on line 33 of Figure 1.

Figure 4 is a section on line 1-4; of Figure 1'. i

Figures 5, 6, 7 and 8 are detail views.

In these views 1 indicates a plurality of stalls in the barn, 2 the gutter in rear of the stalls and 3 the hay rack in front of the stalls. A framing 4 extends across the front of the stalls and a stanchion 5 is supported by this frame, there being a stanchion for each stall. The lower end of each stanchion is hingedly secured to a part of the framing, as at 6, and the upper end of the stanchion is extended and this extension engages a slot 7 in the horizontal part of the framing.

I Specification of Letters Patent. Patented Aug; 15, 1922. Application filed Ju1v'9, 1921. Serial 110.483,!588. i

Thus each stanchion," may have rocking movement in a longitudinal direction in respring 9 tends to hold the stanchion in engagement with the stall end of the slot. A shaft '10 is suitably,jour'naled in the bar above the hay rack and this shaft carries sprocket wheels 11 which are engaged by the rack bars. These wheels are provided with flanges'which act as guides for the bars and the teeth on the rack bars are so formed that when the 'stanchions are moved forwardly the wheels on the shafts will be revolved but on the return movement of the stanchions, by the springs, the teeth will ratchet over thewheels so that the wheels will not be rotated.

A shaft 12 is suitably journaled in the lower part of the barn and this shaft carries the sprocket wheel 13 which is connected with a. similar wheel 14 on the shaft 10 by the chain 15 so that the movement .of shaft 10 will be imparted to shaft 12. Shaft 12 is geared to a shaft 16 on which is mounted the drum 17 for the conveyor 18 which is arranged to pass along the gutter, the other end-of the conveyor being supported by the drum 19 on shaft 20. This conveyor is preferably formed of chains having angle iron cross bars thereon which act as scrapers for removing the material from the gutter. This conveyor can be arranged to convey the material to a pit or other receiver.

One member 21 of each stanchion is hinged to the other part, asat 22, so that this member can be swung away from the other member to permit the cow to place her neck between the two members. The two members are held together so as to hold the cows neck between them by the ring-shaped latch 23. A screw bolt 24 passes through a hole in the stationary member and engages the movable member and this bolt acts as an adjustable means for limiting the outward swinging movement of the movable member. 7

From the above it will be seen that when the cow reaches for the hay or other feed in the hay rack she-will cause the stanchion to swing outwardly or forwardly so as to cause the rack bars to rotate the sprocket wheel and thus rotate the shaft and as this shaft is attached to the conveyor the conveyor will be moved a certain distance along the gutter. .As the cow steps back the spring will return the parts to normal po sition and in this action the rack bar will simply slip over the ratchet wheel without turningthe same on the shaft. Thus the gutter will be kept clean by the movement of the cows and the greater number of cows the greater the movement of the conveyor will be so that there is no danger of the apparatus failing to practically clean the gutter due to the increase of the number of animals in the barn.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claims.

What I claim is:--

1. In a barn, a movable stanchion adapted to be moved bythe animal in reaching for its feed, a driven member, cleaning means actuated by said member and means for imparting the movement of the stanchion to said member.

2. In a dairy barn, a movable stanchion adapted to be moved by the cow in reaching for its feed, a gutter cleaner and means for imparting the movement of the stanchion to the gutter cleaner.

3. In a dairy barn, a movable stanchion adapted-to be moved by the cow in reaching for her feed, a rotary shaft, a sprocket wheel thereon, a rack on the stanchion engaging said wheel, a driven member and means for driving the same from the shaft.

acaaaee 4:. In. a dairy barn, a movable stanchion adapted to be moved b the cow in reaching for her feed, a rotata le shaft, a sprocket thereon, a rack on the stanchion for engaging said sprocket, a gutter cleaner including a shaft, a second shaft geared to thecleaner shaft and means for driving the second shaft from the first mentioned shaft.

5. In a dairy barn, a "movable stanchion adapted tobe moved by the cow in reaching for her feed, spring means for holding the stanchion in its rearward position, a rack bar on the stanchion, a rotary shaft, a sprocket thereon engaged by the rack bar upon the forward movement of vthe stanchion, saidbar ratcheting over the wheel in the rearward movement of the stanchion, a gutter cleaner and means for driving the same from the shaft.

6. In a dairy barn, a stanchion hingedly supported at its lower end, a frame havin a slot therein in which the upper end 0 the stanchion engages, ratchet mechanism connected With the upper end of the stanchion, a gutter cleaner and means for driving the same from the ratchet mechanism.

7. In a dairy barn, a plurality of movable stanchions adapted to be moved by the cows reaching for their feed, a shaft, a plurality of sprockets thereon, a rack bar connected with each stanchion and engaging one of the sprockets, a gutter cleaner and means for driving the same from the shaft.

In testimony whereof I afiix my signature.

ISAAC II. EVANS.
